“From hunting for a film location, shooting auditions, to doing a documentary on the filming process, everything was shot with the iPhone 4,” Mr. Park said after the screening. “We went through all the same film-making processes except that the camera was small.”

The movie, made on a budget of $130,000 is set to open in South Korean theaters on Jan. 27.
